Line 5: [[File:Punct.png\|thumb\|600px\| Short illustration of the puncturing procedure.]] ~~In some cases, a~~A pre-defined pattern of puncturing is used in an encoder, in some cases. Then, the inverse operation, known as depuncturing, is implemented by the decoder. Puncturing is used in [[UMTS]] during the rate matching process. It is also used in [[Wi-Fi]], Wi-SUN, [[GPRS]], [[EDGE (telecommunication)\|EDGE]], [[DVB-T]] and [[Digital Audio Broadcasting\|DAB]], as well as in the [[Digital Radio Mondiale\|DRM]] Standards. Puncturing is often used with the [[Viterbi algorithm]] in coding systems.
